Science
Mechanism of Action
It acts by forming a flexible, uniform film on the skin surface, which contributes to a smooth tactile sensation and improved pigment retention. In hair applications, it prevents stickiness and clumping, adhering effectively while resisting removal.

Formulation
Stability
The copolymer's water solubility and dispersibility improve significantly when neutralized with a base, typically clearing from an opaque mixture as pH rises above 6.0.
Conflicts
- Low pH environments (causes precipitation/turbidity)
- Strong cationic surfactants
- High concentrations of electrolytes (may affect viscosity/film integrity)
